Hi there, the game is unplayable for me as there is a constant stutter/mouse lag.
I'm running it on a laptop with i5 Intel HD graphics.
I've tried forcing V-sync on and off, have updated all drivers and reinstalled numerous times but still the same.
The CPU isn't maxed out or anything.
Any advice?

Re: Stuttering Intel HD
It seems laptops are cursed somehow. I run the game with a desktop i5/HD4000 and it is just sweet. I was worried when i read that HDseries were not officially supported but it seems they only cause probles on laptops or when it's the HD3000 series.
HD4000 runs fine.

Re: Stuttering Intel HD
Hi guys. Yes, the Intel HD series is inconsistent which is why we specified that they aren't officially supported. That said, I've seen the game running just fine on the 3000 line so it's possible to get it to work. Often times it just requires finding the right driver version. Did you reinstall/update your drivers using your laptop manufacturer supplied drivers, or directly from the Intel website? I'd recommend trying to get them directly from Intel.
Sorry about the problem.

Re: Stuttering Intel HD
edit: LOL, I'm an idiot.
Good work implementing the fixes so quickly in the beta patch.
[spoiler]
I see that wglSwapBuffer() is being called very-frequently.
I read that wglSwapBuffer() by default waits for a buffer AND V-Sync unless wglSwapIntervalEXT(0) is used to disable V-Sync, or the drivers being more robust than Intel currently provides.
Adding this as an option may be adequate.
Without decompiling I can only guess that the buffer swaps happen immeadately after rendering- would it be practical to put the game logic between the render and buffer swap as suggested on the linked StackOverflow?
I did try triple-buffering on my machine with V-Sync on, and that too did seem to relieve my mouse lag but also had frequent memory access violations, even managing to crash my browsers (my video drivers were likely to blame).
